Scientists from Vyatka State University (Vyatka State University) claim that it is possible to manufacture durable parts for modern energy from existing domestic steels using the method of electrochemical deposition. They say this improved method makes the elements resistant to high temperatures between 800 and 900 °C. A study of the results was published in the journal Energies.
In various industries, there is a high demand for materials that can withstand high temperatures. Representatives of Vyatka State University said that it is important for high-efficiency fuel cells to withstand high temperatures.
Solid oxide fuel cells (SOFC) are considered the most demanded in the industry. Unlike other fuel cells, they use different types of fuel such as hydrogen, ammonia and syngas and have a high coefficient of performance (COP) of around 70%. However, they operate at high temperatures (700–1000 °C) and require materials with high heat resistance.
Previously, refractory materials for SOFCs had to be purchased from abroad, and they were so expensive that they accounted for more than half of the cost of the entire plant. Anton Kuzmin, head of the Vyatka State University Department of Inorganic Substances Technology and Electrochemical Production, announced that now Vyatka State University offers a technology for the production of these elements from affordable domestic steel.
The researchers used an electrochemical coating technique in which a thin layer of another metal is applied to a metal piece. Through the selection of reagents and steel samples, the experts have developed a manufacturing process that provides heat resistance in the range of 800 to 900 °C. The scientist added that the resulting coatings have low electrical resistance, which increases the efficiency of the fuel cell.
Leading Research Institute Oleg Elkin said that this method can provide a SOFC service life of up to 100,000 hours and can be used to create new materials and technologies in various fields, including energy, aerospace, mechanical engineering and other industries that require special resistance at high temperatures.
